Hi,
I finally got my rig working and am using this cool tool.
I do have one issue though. Under windows I can get 31.8MH/s at 102W, but under Linux I can only get 27.6MH/s and am using ~40W more power.
The BIOS has been modded and the voltages have been set to 950mV.
The cards that I am using are the Sapphire Nitro+ 8GB rx580 special edition (blue case, has both Samsung and Hylinx memory).

There are several users here, where some have reported better values than under windows.
Would you be able to share your bios files, so that i can see where I messed up?
I really do not want to mine under windows.

Thanks
Martin
